Our Litespeed version is 4.0.1 (I don't know if our hosting provider is using a legal version, I would like to know )

Server Info:

CENTOS 6.5
PHP 5.4.28
MySQL 5.5.36-cll

Our hosting provider is trying to solve the problem but I don't think they are really experienced.

How can we solve the problem ? Is there someone or some trusted service we can get to have our server anaylzed? I have SSH/WHM access to my server and I can provide you all the other info. I just want to solve the problem.

It should be disabled forever from XenForo admin section.
Or at least make that terrible option disabled by default so user can choose to enable it latter.
Because mostly websites in this entire world using shared hosting, not all of them using dedicated server per site/forum.
